In r2903:

• use UPPERCASE characters in transport type in SIP Via header, some endpoints complain about it (thanks Tzury Bar Yochay and Alain Totouom for the report)

[bennylp]

In r2906

• fixed crash in pjsua application during shutdown with STEREO_DEO (thanks Andreas Ahland for the report). The STEREO_DEMO in pjsua application was not an accomplished one. It crashed because during shutdown pjsua destroy the app pool without unregistering the splitcomb channel from the bridge first, and that's because the app doesn't keep the splitcomb instance in the first place. Thanks Andreas Ahland for the report.

In r2907:

• r2906 accidentally left STEREO_DEMO option ON in pjsua

[bennylp]

In r2908:

• Updated the doxygen comment/documentation in pj_gethostname() that specying IPv4 address will fail on some platforms (e.g. Windows). Thanks Robert Cichielo for the report.

In r2923:

• increase CSeq on retrying MESSAGE request due to 401/407 response (thanks Rafael Maia for the report)

[nanang]

In r2925:

• WMME dev should zero-fill WAVEFORMATEX as much as WAVEFORMATEX struct size, instead of just PCMWAVEFORMAT size, as it potentially leads to WAVERR_BADFORMAT when it is used in opening audio device (thanks Johan Lantz for the report).

[bennylp]

In r2938:

• fixed misc compiler warnings with gcc on Linux

[bennylp]

In r2949:

• pool that is used to add missing ";lr" parameter in the Route URI is not destroyed in PJSUA-LIB, causing potential memory leak

[bennylp]

In r2954:

added couple of SIPp scenario XML files for future use:

• uac-subscribe.xml: generic subscriber
• uac-options.xml: send OPTIONS

[nanang]

In r2969:

• Updated active socket to keep passing the packet pointer, instead of NULL, when connection is closed/error and no remainder data, as application, e.g: SSL sock, may need to have access on it.

[nanang]

In r2975:

• Fixed pjmedia Makefile build config to clean pjmedia-audiodev component properly.

[bennylp]

In r2978:

• renamed "mips" variable in pjmedia MIPS test since it conflicts with some internal name in MIPS target (thanks Antonio Anton for the report)

[nanang]

In r2983:

In r3012:

[bennylp]

In r3013:

• undo r3012, and silently adjust max_calls to PJSUA_MAX_CALLS instead if it is greater (thanks Robbie Hanson for the suggestion)

[nanang]
